Forward-Phase Dimmer–Gen 2
Prepare for Installation
The Forward-Phase Dimmer–Gen 2 is designed for mounting directly to an
electrical junction box or panel (provided by others) at the electrical lighting
load, upstream of the load in the circuit.
Note: If your installation requires Class 2 wiring to be installed in
separate conduit, a voltage barrier installation box is available from ETC.
Order ETC part number 7187A1000.
EchoConnect Control Wiring
The Forward-Phase Dimmer–Gen 2 connects to the EchoConnect station
communication bus for control. EchoConnect is a bidirectional protocol that
uses one pair of wires (data+ and data-) for both data and power. ETC
recommends using Belden 8471 (or approved equal) Class 2 wire. The total
combined length of an EchoConnect wire run (using Belden 8471, or equal)
may not exceed 500m (1,640ft).
Note: All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation practices.
Leave approximately 20cm (8in) of wiring in the back box for connection
and to allow slack for future service needs.
Note: ETC requires that all Echo stations and devices be grounded for
ESDprotection. Pull an additional 2.5 mm2(14AWG) wire for grounding
when control wires are not installed in grounded metal conduit.

Assign Zones and Spaces
Rotary
switches
You can assign zones and spaces using
the two rotary switches on the side panel
of the controller.
By default, these switches are set to
Zone1, Space 1. Control inputs from the
connected stations, sensors, and other
controls are shared by all devices within a
space.
1. Set the Zone rotary switch to the
desired Zone address for this
controller.
2. Set the Space rotary switch to
the desired Space for this
controller.
Power Up and Test
1. Restore power to the circuit. The
Forward-Phase Dimmer–Gen 2
will power up and turn on all connected loads to full output.
2. Test the circuit by activating the associated Echo station preset or by
changing the zone intensity control.
3. Test the controller response. Use station controls to alter preset or
zone status, and ensure that the Forward-Phase Dimmer–Gen 2
responds.
Power-Up Behavior
In the event of a power loss to the Forward-Phase Dimmer–Gen 2, the
controller will return to its last output level when power is restored.

Set the Dimming Mode
Use the Dim Mode button to manually set the dimming mode or to enter
Fluorescent Voltage Adjustment mode. The related LED indicates which mode
is currently active.
Press the Dim Mode button to toggle the dimming mode:
•
Linear: The linear curve matches the control input percentage to Root
Mean Squared (RMS) voltage output. Each percent increase in control
level increases dimmer voltage output by the same amount.

•
Modified Square Law (Mod-Square): A standard square law curve
may overcompensate for infrared loss, resulting in “steppy” response
to incremental control changes at low levels. This modified square law
curve applies a second multiple to the standard square law curve for
more uniform response to control levels changes across the entire
range of dimmer output.

Fluorescent Voltage Adjustment Mode
This mode adjusts the minimum turn-on voltage used by Fluorescent dimming
mode. Press and hold the Dim Mode button for 5 seconds to enter
Fluorescent Voltage Adjustment mode. The LED is amber when this mode is
active.
Note: The allowed range is 0–100% of the input voltage. By default,
120 VAC models are set to turn on at 56 VAC, and 277 VAC models are
set to turn on at 129 VAC.
Press the Dim Mode button again to increase the “turn on” voltage by 2%,
or press the Dim Phase button to decrease the “turn on” voltage by 2%.
Because the Forward-Phase Dimmer–Gen 2 outputs at the current turn-on
level while in Fluorescent Voltage Adjustment mode, you can make
adjustments with the loads on, regardless of the input control state.
Press and hold the Dim Mode button for 5 seconds to save the setting and
exit Fluorescent Voltage Adjustment mode.
Troubleshooting
Error Indicators
The Dim Phase LED and Dim Mode LED (see image on page 1 ) double-blink
red in unison when the dimmer is too hot. Ensure that the dimmer is in a
suitably air-conditioned space and that free air is able to move around the
heat sink.
Restore Defaults
To return the Forward-Phase Dimmer–Gen 2 to factory defaults, set both
rotary switches to 16 and then press and hold both the Dim Mode and the
Dim Phase buttons for 10 seconds. The LEDs will blink red quickly to indicate
that the factory defaults have been restored.
Note: After you return the Forward-Phase Dimmer–Gen 2 to factory
defaults, reset the rotary switches to the appropriate values for the
controller zone and space.

•
The Dim Mode LED will illuminate amber in a triple-blink
pattern while the firmware is updating, and then will return to its
previous state when the update is complete.
•
If the LED illuminates red in a double-blink pattern, an error has
occurred. Ensure that the firmware file has not been renamed
and is located at the root directory on the microSD card, and then
attempt the firmware update again. If the LED continues the
double-blink pattern, contact ETC Technical Services using the
information at the bottom of page1.
